Using Proxy Switch to Calculate RPM

[zero118]

Okay, I'll give the period strategy a shot! Thank you!

Also, i thought I should use the reset function because I wanted to find a relatively instantaneous rpm, which is also the reason I wanted to calculated the rpm every second using the time tasks VI. I thought if i didn't reset the counter, it would give me an average rpm, which would not be very useful. Am I interpreting it wrong?

Thank you again for the replies!
